Returns a new DateTime that adds the specified number of milliseconds to the value of this instance.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Double
The number of whole and fractional milliseconds to add. This value can be positive or negative, and is rounded to the nearest integer.
Return ValueType: System.DateTime
An object whose value is the sum of the date and time represented by this instance and the number of milliseconds represented by value.
The fractional part of value is the fractional part of a millisecond. For example, 4.5 is equivalent to 4 milliseconds and 5000 ticks, where one millisecond = 10000 ticks.
The value parameter is rounded to the nearest integer.
The following example uses the method to add one millisecond and 1.5 milliseconds to a DateTime value. It then displays each new value and displays the difference between it and the original value. The difference is displayed both as a time span and as a number of ticks. The example makes it clear that one millisecond equals 10,000 ticks. It also shows that fractional milliseconds are rounded before performing the addition; the DateTime value that results from adding 1.5 milliseconds to the original date is 2 milliseconds greater than the original date.
